HEATING AND VENTILATING APPARATUS.

Application filed December 7, 1925. Serial No. 73,946.

My invention relates to heating and ventilating units. I

It is my object to provide a heating and ventilating unit of the minimum height and width. in which the air resistance will. be reduced to a minimum, by the arrangement or" the parts, as set forth herein.

In detail, it is my object to provide a simplified form of bottom intake and recirculating damper, an improved form of deck between the. blower housings and the radiator to eliminate eddy'ing currents and to secure a more regular flow of air.

It is a further object to provide a radiator which'is completely enclosed, both top and bottom, when the air is by-pa'ssed, thus preventing stray eddying currents from entering the radiator, circulating through the coils and eventually finding their way up the by-pass carrying with them considerable heat.

It is a further object to provide a novel form of blower mounting.

It is my object to provide a stream line apparatus aifording the least resistance tov the passage of air.

Referring to the drawings: 4

Figure 1 is a front elevation of? the complete housing with the front door partially broken away and with the blower casing and deck partially broken away;

Figure 2 is a section on the. line 2---2. of Figure 1;

Figure 3 is a view of the cabinet with the front door open, with the radiator unit and the blower and deck unit removed to show the detachability of the structure. its ease of assembly and ease of cleaning;

Figure 4 is a perspective of the complete unit of the blower and its deck. 1

Referring to the drawings in detail, 1 is the bottom of the unit casing having a rear wall 2, which abuts against the inside of the. building wall. is provided with an opening 3 through which the air passes from the outside. A swinging front door 4 is provided with end walls 5 and 6' completing the casing save for the top which is composed of a flat portion 7 and a diagonally-disposed portion 8 which has a series of perforations to form a grill. This top can be lifted off of the casing as it rests on the rear and the side walls.

The portion 7 is provided with a depend- Thebottom of this Wall" ing, parallel strip spaced therefrom, designated 9, which is adapted to engage with the transverse, overhanging angle iron 10 along the upper inside margin of the rear wall 2. This top is provided with overhanging flanges 11,'which rest on the side walls 5 and 6. Thus the top can be taken off easily for cleaning of the upper part of the structure.

In the side walls in the lower half of the structure is pivoted on the transverse support 12 a damper consisting of portions 13' and 14 which serve to close the inlet air opening, and portions 15 and 16 which serve to close the re-circulating opening 17 in the form of a grill in the lower part of the front door 4 of the front wall casing.

Beneath the pivotal support 12 is atransverse vertical plate 18 carried on the bottom 1 of the casing. It will be noted from the arrangement of the casing that the damper can control the introduction of the air from the outside or from the inside of the room, according to the Setting thereof. To insure this, there is a transverse partition 19 having an air opening 20,,whic-h insures that the air will pass upwardly within the casing into the eye 21 of the blower casings 22 and 29. The blowers and the motor are resiliently supported through the motor 23 having its feet 24: resting on a transverse platform 25 which is hung on spring supports 26 that have their lower-ends resting upon the transverse member 27 v and the platform 28. The blower casings 22 and 29 are suspended at 30 from the transverse, horizontal deck 31 which is extended midway the depth of the casing upwardly and inwardly towards the room, as at 32, to a point where it joins the door of the casing just at the corner of the radiator 34, as at 35.

reached by opening the door of the cabinet. I

This counter weight 39 is installed within a chamber 41 formed by the end walls 6 and an enclosing bracket 42, which serves as a support for the shaft 37- at one end. The other end of this shaft 37 is supported on a bracket 43 on the side wall 5, which forms a chamber 4 for housing the three-pole key switch 45. Mounted on these bracket supports 42 and 43 are the ends 46 of the radiator 34. These ends are provided with horizontal guides 47, which rest upon the steel radiator wedges 48 that are, in turn,

supported on the bracket 42 and 43. Thus, it is pos ible to install the radiator and wedge it in the proper position or detach it, as desired. The upper portions of the ends of the radiator are provided with similar guides 47 so that the radiator is guided into position beneath the overhanging ledges 49 carried on the end walls 5 and 6. An upper wedge is provided adjacent the wall 5 for locating the radiator. The radiator is enclosed on one side by the door and on the rear by the upwardly extending wall 50, which extends from the damper 36 upwardly to the top of the radiator then inwardly at 51 to the angle iron 52 which forms one wall of the room 53 around the mouth 54 of the opening above the radiator. The remainder of this cap plate is designated 55 near the front wall of the casing. Thus, the radiator is completely enclosed save for the lower opening through the passageway 56 and the upper opening through the passageway 54. This upper opening 54 is closed by the mixing dampers 57 and 58 which are connected to the links 59. These links are, in turn, connected to a bell crank 60 pivoted at 61 on a side wall of the casing. A connecting link 62 is connected to the bell crank at one end and to the counter weight of the damper 36 at the other.

It will be noted that this damper 36 either closes the passageway 63 or the passageway 56. It will be further noted that when the passageway 56 is closed, the dampers 57 and 58 will be closed, and that the radiator will be completely enclosed, so that no air can touch it in any way.

A knob 64 is adapted to control the mixing dampers and a knob 65 controls the inlet damper.

The frame 27 carries a plurality of up rights 66 which serve as guides to assist in maintaining in proper position the blower ca ings 22 and 29.
